So, I was watching basketball on CBS HD (MSU giving OSU a run for their money), and frankly, it didn't look that good. That is, it looked good, but had a few focus problems, a bit of blurring. Now I'm watching CSI-Miami, and it looks GREAT.

The reason for this is, of course, obvious.

Basketball - 1080i/60fps

CSI-Miami - 1080i/24fps


Everyone knows that Fox, ABC, and ESPN, broadcast HD in 720p (NBC and CBS both use 1080i). ESPN says they do this because 720p/60fps looks better than 1080i/60fps. Watching a comparison of live sporting events, I'm inclined to agree.

That said, I'm worried now that the super bowl is going to look crappy, as CBS is going to be broadcasting it in 1080i/60fps.

Anyone agree?

They will use the best equipment for the Super Bowl. They will make sure the picture looks great.

Yeah, 720p is better than 1080i for sports, because interlaced pictures only refresh every other line on each pass, this only 540 lines are refreshed on each pass in 1080i, whereas all lines are refreshed in a progressive picture, thus all 720 lines in a 720p are refreshed at once.

The consequence is that 720p is better for sports (or anything in which there is a lot of rapid movement). 1080i is generally considered better for movies, where there is less rapid movement.

Of course, you need a really big TV to tell the difference (probably 40" +) and either way it is better than the standard 480.

I don't think it's a matter of equipment. I really do think 1080i looks better for movies (because movies have a lower framerate), but 720p seems to work better for live television. Unless they're planning on changing that... I don't know how they could make it look better.

wait, doesnt 1080i@60fps = 1080p?

just wonderin.

Because there ARE 1080p tvs out there, just not many.
No, 1080p is progressive while 1080i in interlace. They are 2 different resolutions.

1080p is the highest resolution but I don't think any networks are broadcasting it in because the bandwidth is so high.

1080p30 is as high as current bandwidth will allow. With newer codecs, 1080p60 will be possible.

Is anyone currently using 1080p, I don't think any networks are using it yet and far fewer cable providers are offering it.
